You can often repair stiff
chain links with oil or careful
lateral bending. Severe cases will
require replacement of links.
Links are replaced in pairs, an
inner link and an outer.
1- and 3-speed bikes use 1/8"
wide chain, for which you buy
master links. These snap on
easily.
Derailleur-type bikes have no
master link, all the links are the
same. For these chains you need a
chain tool. This tool drives a
rivet of any link almost all the
way out of the link, making it
possible to separate the chain.
Never drive the rivet entirely

out, since you will not be able to
re-install it. After your chain
repair is complete, simply drive
the rivet back into position. If
stiff, bend the link laterally
(carefully) to make it flexible
again.
With care, you can use a
hammer and a nail instead of a
chain tool to drive a rivet out.
If you are putting a new
chain on a derailleur bike, the
correct length is the longest
possible while engaged on the
smallest rear and smallest front
sprockets without sagging.
